Can I use a femoral lines to measure CVP?


When the IJ or subclavian site are not options, the femoral location is a good back-up option for obtaining central venous access. 


The question of whether or not you can reliably obtain a central venous pressure from these lines was investigated in a short review in Emergency Medicine Journal which focused on the results of 9/141 studies found in their medline search.

Take home message:


·         The readings from IVC (femoral lines) appear to be about 0.5mm Hg lower than the SVC (IJ and SC lines) readings and were rarely more than 3mm Hg different. 

·         The only subset of patients that this may not be accurate is in patients with abdominal compartment syndrome (ref: Crit Care & Shock 2008. Vol 11, No. 3)
